Replace {...} with actual content.
Formal plan packages include the scoring block by default.
blueprint/README.md stays as a lightweight index only.
If extra long-lived topic docs exist at the blueprint/ root, they must be linked explicitly from blueprint/README.md.
blueprint/tasks.md keeps only unfinished long-term items and explicit deferrals; completed items do not remain in that file.

# Project Technical Conventions

## Tech Stack
- Core: {language version} / {framework version}
- Build: {build tool}
- Test: {test framework}

## Working Agreement
- Keep this file focused on reusable technical conventions.
- Do not treat one-off implementation choices as project-wide rules.

## Document Boundaries
- `project.md`: reusable conventions
- `blueprint/background.md`: long-term goals, scope, non-goals
- `blueprint/design.md`: module / host / directory / consumption contracts
- `blueprint/tasks.md`: unfinished long-term items and explicit deferrals

# Project Blueprint Index

Status: {current status}
Maintenance: keep only status, current goal, current focus, and read-next links on this page; move long explanations into other blueprint files

## Current Goal
- Project: `{project_name}`
- Long-term goals and scope live in `./background.md`

## Current Focus
- Active plan: {present/none}
- History archive: {status}

## Read Next
- [Technical Conventions](../project.md)
- [Blueprint Background](./background.md)
- [Blueprint Design](./design.md)
- [Blueprint Tasks](./tasks.md)
- [Blueprint Topic](./{extra_blueprint_doc}.md) # list each additional long-lived topic doc when present
- [Change History](../history/index.md)

# Blueprint Background

## Long-Term Goals
- {goal1}
- {goal2}

## Scope
- In scope: {content}

blueprint/design.md

# Blueprint Design

## Formal Contracts
- `knowledge_sync` is the only formal sync contract.
- `active_plan = current_plan.path + current_plan.files`.

## Consumption Contract

| Context Profile | Reads | Fail-open Rule | Notes |
|-----|------|------|------|
| `consult` | `project.md`, `preferences.md`, `blueprint/README.md` | missing deep blueprint does not fail | do not force plan materialization |
| `plan` | `L1` + `active_plan` | materialize deep blueprint by lifecycle when missing | history is not default context |
| `finalize` | `active_plan`, `knowledge_sync`, `blueprint/*`, `history/index.md` | create `history/index.md` on demand when missing | block when `required` sync is not satisfied |
